A bill to amend the Foreign Intelligence Surveillance Act of 1978 to prohibit the use of authorities under such Act to surveil United States persons and to prohibit the use of information acquired under such Act in any criminal, civil, or administrative proceeding or as part of any criminal, civil, or administrative investigation.

S4998 was introduced in the Senate on July 15, 2026, and referred to the Committee on the Judiciary. Sponsored by Sen. Rand Paul (R-KY), the bill seeks to restrict the use of FISA authorities for surveillance of U.S. persons and to prevent the use of information obtained under FISA in criminal, civil, or administrative proceedings or investigations. The bill is in the earliest legislative stage with no cosponsors and no committee action beyond referral. The legislative path requires committee markup, floor debate, and passage, which is unlikely given the lack of bipartisan support and the controversial nature of restricting surveillance tools. The bill authorizes no funding and does not create any procurement or spending program. Its impact on the private sector is minimal; companies that provide surveillance technology or data services to the government could face reduced demand if the bill were enacted, but passage is highly uncertain. The bill is a standalone measure with no related bills, amendments, or committee reports indicating momentum. For investors, this is a low-impact, procedural event with no actionable financial signal.
